PARACHUTE DEVICE.

Specification of LettersPatent.

Be it known that I, ANTON OISTER, sub- Emperor of Austria-Hungary, nter Siska, near Laibach, in the mpire of Austria-Hungary, have in-' vented certain new and useful Improvements in Parachute Devices, of which the followto a parachute device more particularly for use in connection with aircraft.

The object of the present invention is to an improved parachute device which shall b very simple in construction and reliable in operation and one that can be easily carried on the back .of the user and also easily mounted on an aerial craft.

e parachute according to the; present he present invention relates invention is adapted td be brought into the,

vision on the material forming th cry of theparachute,1o'f pivoted links, which th may be lazy tongs adapted to .be contracted when the parachute isin thecollapsed condition and therefore take up very little space; while when the collapsed parachute is opened, the lazy-tongs openautomatically by means of springs provided on the articulations, and In th is manner open the para- Two embodiments of the.

On the cry of the parachute proper it, lazy-tongs! are provided according to this construction, e crossing points are also tending to open or extend the lazy-tongs. When not in use the lazy-tongs are contracted against 'the he parachute housed within the casing on bottom is whic is retained in a position placing the springs f under tension. When this retaining device is released, the springs pro ect the bottom It with the parachute parachute which Patented May 4, 1915. Application filed January 6, 1914. Serial No. 810,594. I

the contracted lazy-tongs is the movable remains connected to the'casing by meansof the cords g withdrawn from the tubes d.

According to the modification illustrated to 7, the mechanism for opening the parachute, instead 01'' consisting of lazytongs, consists of a plurality of rods or the like a, which are connected at their ends, by means of pins 72 so as to form a rim. On these pins', springs are provided in suitable casings g, which have the tendency to turn one another in such a manner that. they form an angle of about between their members. er ,0 is secured, about 11 the collapsed condlt on of the parachute, the members are contracted in a zig-zag manner similarly to a contracted rule, so that the rim formed by the rods'takes up very little-space and the parachute connected with. this e housed in the casing. When the para a which is considment the weight siderably reduced.

forms an undawirable load ered for the sake of safety only, particusuch a manner as to f the releasing device being aerial craft,

desired, by the ada ted to be operated, if

What I claim and desire to secure by Letters Patent of the'United States is:- 1 1. Apparatus of the character described, comprising in combination a parachute, a

receptacle adapted to normally contain the parachute in a collapsed condition, means connecting the parachute to the container, a locking device normally retaining the parachute within the receptacle, means for releasing the locking device, lazy-tongs provided on the periphery of the parachute, and springs at the joints of the lazy-tongs for the purpose of automatically expanding the lazy-tongs when the parachute leaves the-container, for the purpose specified. 2. Apparatus of the character described, comprising in combination a parachute, a receptacle adapted to normally contain the parachute ilia collapsed condition, means connecting the parachute to the container, a locking device normally retaining the parachute within the receptacle, means for releasing the locking device, means for caus ing the parachute to leave the container when the loc" g device is released, lazy-tongs provided on the periphery of the parachute, springs at the joints of the lazy-tongs for the purpose of automatically expanding the lazy-tongs when the parachute leaves the container, paratus upon and means for securing the appurpose specific the back of the user, for

3. Apparatus of the character described, comprising in combination a parachute, a receptacle adapted to normally contain the parachute in a collapsed condition, means connecting the parachute to the container, a locking device normally retaining the parachute within the receptacle, means for releasing the locking device, lazy-tongs provided on the periphery of the parachute,

' springs atthe jointsof the "lazy-tongs for the purpose of automatically expanding the lazy-tongs when the parachute leaves the container, and means for securing the .apparatus upon the back of purpose specified.

4. Apparatus of the character described,

comprising in combination a parachute; a

the user, for the receptacle adapted to normally contain the a parachute in a collapsed condition, cords connecting the parachute to the container, a locking device normally retaining the parachute within the receptacle, means for releasing the locking device, means ing the parachute to be projected automatically from the container upon release of the locking device, lazy-tongs provided on the periphery of the parachute, springs at the joints of the lazy-tongs for au to-- for cau's-' matically extending the lazy-tongs when the parachute leaves the contalner, and means for. securing the apparatus upon the back of the user, for the purpose specified.

5. In a device of the kind combination of a parachute, adapted to normally contain the parachute in a collapsed condition in order to house described, the a receptac e.

the parachute in a small space when moperative, the container, a locking device normally retaining the parachute within the receptacle, means for releasing the locking device, means within the container for automaticords connecting the parachute tocally projecting the parachute surface therefrom upon releasecf'the locking device, an automatically extensible rim on the periphery of the parachute comprisin a plurality of members pivotally connecte together at their ends, pivots upon which each of these members are m disposed at the centers of these members and adapted to connect them to the parachute and springs mounted at the joints of these members for automatically extending therim when the arachute leaves the container, and straps or securing the apparatus upon the back of the user, for the specified.
